Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646374, here are decompositions:

13 + 8646361 = 8646374
97 + 8646277 = 8646374
127 + 8646247 = 8646374
151 + 8646223 = 8646374
193 + 8646181 = 8646374
211 + 8646163 = 8646374
271 + 8646103 = 8646374
313 + 8646061 = 8646374

Showing the first eight; more decompositions exist.
